Software sizing problems in software engineering metrics
Edward G. Rodgers · 1988
Effort estimation models such as COCOMO (COnstructive COst MOdel) or COPMO (COoperative Programming MOdel) typically use KDSI (thousands of delivered source instructions) as the primary input variable to determine person-months and development time for software development projects. Such models have the general form [BOE81], [CON86]: E = @@@@ where n = number of modules E = effort, in man-months (MM) S = software sizing estimate (KDSI) a,b = development mode constants c1 = complexity multipliers based upon project conditions
